Pam Chemical Water Treatment Cationic Polyacrylamide Flocculant
Cationic polyacrylamide (CPAM) is a kind of copolymer composed of cationic and nonionic units of acrylamide. Its molecular chain has ionizable positively charged groups (-CONH2), which can be ionized into polycations and polycations in water. Small anions can adsorb and bridge suspended particles dispersed in the solution, and have a strong flocculation effect.
Cationic polyacrylamide is widely used in water treatment, metallurgy, papermaking, petroleum, chemical, textile, mineral processing and other water treatment fields. It is used as thickener, flocculant, drag reducer, and has the functions of gelation, sedimentation and reinforcement. The molecular weight of CPAM is generally lower than that of NPAM and APAM, and it is especially suitable for dewatering treatment of industrial sludge such as municipal sewage, municipal sludge, and paper sludge.

Ionization degree:
The cationic degree is the charge density of the CPAM molecular chain. The degree of cation is one of the determinants of the flocculation effect. If the ions are too low, the floc has little or no effect. If the ions are too high, the sludge flocs will be repelled due to excess charge. Therefore, for the sludge to be dewatered, flocculants with different ionic degrees can be screened out through small experiments, and the best and suitable polyacrylamide can be selected, which can not only achieve good flocculation effect, but also minimize the addition of chemicals. . .quantity. cost. The main points of ion selection:
(1) Size of flocs: Too small flocs will affect the drainage speed, and too large flocs will bind more water and reduce the degree of mud cake. The size of the floes can be adjusted by choosing the molecular weight of the polyacrylamide.
(2) floc strength (water content): flocs should remain stable without breaking under shearing action. Increasing the molecular weight of polyacrylamide or selecting a suitable molecular structure can help improve the flocculation stability.
